• OEUK is asking Chancellor John Healey to start the Oil and Gas Revenue Levy in 2027 instead of the legislated March 2030 date.
• The OGRL applies a 35% levy only when oil tops $90/barrel or gas tops 90p/therm, replacing the Energy Profits Levy's contribution to a combined 78% headline rate.
• OEUK's £14.9 billion revenue estimate and 111-project unlock figure are industry modeling, not a Treasury costing or a confirmed policy change.
• The proposal lands ahead of Chancellor Healey's first Budget in late October 2026, under a government formed after Andy Burnham became prime minister in July 2026.
• OEUK's higher projected North Sea gas output (288 billion cubic meters by 2035) would cut UK reliance on imported LNG, a demand variable relevant to Gulf exporters such as Qatar.

Offshore Energies UK wants the Treasury to swap the Energy Profits Levy for its permanent successor — the price-triggered Oil and Gas Revenue Levy — in 2027, three years ahead of the March 2030 start date already legislated (Rigzone, Sept. 15, 2026). The lobby group's modeling, published in its 2026 economic outlook, puts the payoff at roughly £14.9 billion (about $20 billion; Energy Connects rounds the figure to £15 billion) in additional tax revenue through 2035, split between £2.4 billion in direct industry levies and £12.6 billion in payroll taxes from jobs the group says the earlier switch would preserve or create.

The Mechanism OEUK Wants Early

The Oil and Gas Revenue Levy is not simply a lower rate; it changes the trigger. The Energy Profits Levy taxes North Sea profit at 38% on top of the 30% ring-fence corporation tax and 10% supplementary charge, for a combined 78% headline rate. The OGRL instead applies a 35% charge only when Brent-linked oil clears $90 a barrel or gas tops 90p a therm, reverting to the ordinary 40% ring-fence-plus-supplementary rate below those lines (HLC, 2026). That price-conditionality, not the number itself, is what OEUK is asking Healey to bring forward to 2027.

OEUK's Ledger, Not the Treasury's

Every number in this pitch is OEUK's own modeling, not an independently audited forecast or a Treasury costing. OEUK chief executive David Whitehouse pressed Healey to make the earlier switch as part of the group's Budget submission (OilPrice.com, Sept. 2026). OEUK estimates the earlier switch unlocks £50 billion in private investment and 111 additional projects; none of that capital has been committed, and the estimate assumes producers respond to certainty exactly as modeled.

Why a Crude Desk Reads a UK Tax Story

The North Sea is not a bystander to the Brent complex — it is the physical grade the benchmark is built on, however thin the loading programme has become. A tax regime OEUK says has discouraged investment since 2022 bears directly on how many cargoes still load to keep the Dated Brent assessment window liquid. OEUK frames the 2027 ask as a fiscal-certainty argument; for the benchmark's physical underpinning it is also a supply-side one — reported here as OEUK's claim, not an independently verified production forecast.

The Gas Numbers Matter to Gulf LNG Suppliers Too

OEUK projects UK gas output could reach 288 billion cubic meters between 2025 and 2035 under the earlier regime — 64% above the currently projected trajectory — covering roughly half of domestic gas demand (Rigzone; Energy Connects, Sept. 15, 2026). Every cubic meter produced domestically is one the UK does not need to source as LNG, and Gulf exporters, Qatar chief among them, compete for that same import slot against Asian buyers. A materially higher North Sea output path is a demand-side estimate worth tracking, not a settled fact.

What to Watch

Chancellor John Healey, who returned to the Treasury after Andy Burnham became prime minister on July 20, 2026, delivers his first Budget in late October 2026 (Energy Connects, Sept. 15, 2026). That is the earliest point at which OEUK's 2027 ask could be confirmed, rejected, or deferred; nothing in the group's report obliges the Treasury to adopt an earlier trigger date, and no primary-source confirmation exists that Healey supports moving the OGRL start date.
